Abstract

This paper proposes a compact realization of a phase-noise (PN) improving core-coupling technique for millimetre-wave (mm-Wave) CMOS LC voltage-controlled oscillators (VCOs). The target is to provide a multi-core wideband continuous frequency-tuning-range (FTR) and low PN for FMCW radar applications while maintaining area and complexity at a minimum level. The VCO cores are superharmonic injection-locked at second harmonic (H2) on a common tail node. Three VCOs are fabricated in a 22 nm fully depleted (FD) silicon-on-insulator (SOI) CMOS technology: Single-Core, Dual-Core and Quad-Core. All implementations have the same core design. Measurements show the expected PN improvement for the multi-core VCOs compared to the single-core VCO.
